AT-8000S/48
Layer 2 Stackable Fast Ethernet Switch
AT-8000S/48
48 port stackable 10/100TX Layer 2 switch
with 2 active SFP bays (unpopulated) and
2 standby 10/100/1000T ports (RJ-45)
Overview
One of a series of stackable switches from
Allied Telesis, the AT-8000S/48 provides high
performance Layer 2 switching in an affordable
fixed configuration platform. This switch offers
48 10/100 por ts, two fixed 1Gbps SFP slots
plus two integrated stacking connectors that
deliver a total of 4Gbps stacking bandwidth. The
stacking capability integrated into this platform
is configured as a resilient ring topology
designed to provide high reliability and
simplified management for higher port density
applications.
Ideal Branch Office and Wiring
Closet Connectivity
Powerful line rate performance and stackability
make this switch ideal for branch offices or the
wiring closet of larger offices. The state-of-theart QoS capability of this product ensures
reliable delivery of advanced network services
such as voice while effectively controlling the
continually increasing traffic needs found in
today’s networks.
Easy Access Networking
Featuring an industry standard CLI and Allied
Telesis’ intuitive yet fully featured Web interface
the advanced features of the AT-8000S/48 are
accessible to a wide range of system
administrators. The well known CLI and Web
interfaces significantly reduce learning time and
minimize the cost of deployment.
Secure Management
Only authorized administrators can access the
management interface of the 8000S series.
Protocols such as SSL, SSH and SNMPv3
facilitate this protection of your network with
local or remote connections.
Securing the Network Edge
To ensure the protection of your data, it is
important to control access to your network.
Protocols such as IEEE 802.1x por t-based
authentication guarantee that only known users
are connected to the network. Unknown users
who physically connect can be isolated to a
pre-determined par t of your network offering
guests such benefits as Internet access while
ensuring the integrity of your private network
data.
Gigabit and Fast Ethernet SFP
Support
All switches in the 8000S family suppor t both
Gigabit and Fast Ethernet Small Form-factor
Pluggables (SFPs). This makes the 8000S series
an ideal family for environments where Gigabit
fiber switches will be phased in over time. The
8000S family allows for connectivity to the
legacy 100FX hardware until it is upgraded to
Gigabit. Suppor t for both speeds of SFPs allows
organizations to stay within budget as they
migrate to faster technologies.
